args tag in RIF XML serialization

Hello,

which of the following (partial) XML code is valid RIF XML?

1) No args tag:

<Atom>
   <op><Const type="&rif;iri">http://test.org/P</Const></op>
</Atom>


2) Empty args tag:

<Atom>
   <op><Const type="&rif;iri">http://test.org/P</Const></op>
   <args ordered="yes"/>
</Atom>


In [1] there is no question mark characterizing the args tag as optional,
so I would go for 2 and view 1 as invalid.

By reading the XML schema ([1]) on the other hand I think 1 is valid but 2 is not.

Thanks for your help.
